Another object of the invention is the provision,

of a signal adapted to be secured to the car door and arranged so thatit will fold into the space between the inner panel and outer wall ofthe car door to be entirely concealed. V

Another object of the invention is the provision of a signal which canbe actuated to either operative or inoperative position by a singleflick of the hand. I

Another object which I have in view is the provision of a signal incombination with a clip which releasably holds the signal in either itsoperative or. its inoperative position.

Another object of the invention is the provision of a signal arm of verythin metal construction so that it will pass readily through a narrowslot in the outer wall of the car door, the signal being provided with aplate to entirely conceal the slot when the signal is in its inoperativeposition.

Having in view these objects and others which will be pointed out in thefollowing description, I will now refer to the drawing, in which Figurel is a view in cross section of the car door showing the signal in itsoperative position.

Figure 2 is a view similar to Figure 1 but showing the signal in itsinoperative position.

Figure 3 is a View in perspective of the signal.

member.

Figure 4 is a perspective view showing the signal plate I0 terminatingat its inner end in a hook-like member I I which is formed by cutting anarcuate slot in the plate. A lever arm. I2 projects from the lower edgeof the signal plate 'I I] and this lever arm terminates in a handle I3.The signal plate II] and the lever arm I2 are further comiected by abrace I 4. The parts II],

II, I2, I3 and I4 are integral and they may be,

struck out of ae'single sheetof metal.. For conwenience' the handle I3may be-Lrounded. I The plate'Iiis-secured to the signal-plate W at-" itsupperf'edge' and-transverselythereto so that the Jendel'evatiorr ortransversersection' of the parts Wands IiwillabeiT-shaped {in-.outline.'-.

'As shown in Figures 1 and 2 the signal plat IE! is mounted to swingabout a pin I6 which is secured to the outer wall orthe car door, the

securing means being shown in Figure 4. The car door is provided withavery narrow slit to permit the passage of the signal plate I0, and

the pin I6 is positioned across the slit and spaced inwardly therefrom.Two brackets I! are there- 'iore secured to the outer wall of the cardoor so as to project slightly into the space within the car door.Because of l the arcuate slot the signal plate In it is an easy matterto engage the signal plate In with the pin I6 as shown in Figures 1 and2. When the signal is in its in- 20 operative position as shown inFigure 2 the plate I5 covers andconceals the slit and preventstheentrance of water and. dust or other foreign matter. 7

The inner panel of the car dooris provided with a slot for the movementof the lever arm I2.

Adjacent the slot of the inner panel of the car.

door is a clip I8 as shown in Figures 5 and 6.

This clip is preferably formed from resilient 1 metal which is twistedinto two half turns with projections or bends I9 extending part wayacross the slot as shown in Figure 5.- As shown in full lines in thatfigure the lever arm I2 is in its lowermost position with the signal inits operative position. The lever arm I2 is yieldably held in itslowermost position by the lower of the two bends A slight push upwardlyof the handle I3 will cause the lever arm I2 to ride over the lower bendI9 and then over the upper bend I9 to its dotted line position in Figure5 in which the signal will be in its inoperative position as shown inFigure 2. v The clip I8 is highly resilient and move the signal fromeither position to the other andit is only fora moment that the driverreleases his left hand from the steering wheel. It is necessary,however, to selectsuch a position as not to interfere with the slidingwindows 2 r w 7 ofothe car nor with the door lock or latch. Theinstallationthus necessarily depends to some ex-' tent on the carconstruction'but the arrangement which I show in my drawing is adaptedfor installation in practicallyevery typeof closed car.

7 others skilled in the art to which it pertains,

what I claim as new and desire to secure by Let ters Patent of theUnited States is: s f I 1. In combination, an automobile door -havingspaced apart inner and outer walls each pro-' vided witha vertical slot,a -pivot p'in'se'cured to said outer wall and spaced inwardlyatherefromand transversely of the slot thereof, a signal arm having an open endedarcuate slot at its inner or upper extremity for 'releas'ably engaging'said pivot pin; an arcuate lever projecting from said signal arm andthrough the slot of said inner wall, and a spring cliplsecured tosaidxinner :lwall inside said automobile door; said springcliphavv a inga pair of stops defining the operative and inoperative positions of saidsignal arm.

1 2. In combination, an automobile door having spaced apart inner andouter walls with a hollow space therebetween; said walls being eachprovidedwith a vertical slot, a signal arm having a width materiallyless than the distance between said outer and inner walls, a pivot pinsecured to said outer wall and spaced inwardly therefrom adjacent theupper, extremity of the slot of fsa'id outer wall, said signal arm beingprovided with an open ended arcuate slot at its inneror upper extremityfor releasable engagement "with said pivot pin, a transverselypositioned plate on said signal arm, said plate having substantially thedimensions of the slot of said o'iiter wall whereby said plate will becontinuou'swith said outer wall when said signal arm is in inoperativeposition, an arcuate lever proj'ecting from said signal'arm and. throughthe slot ofsaid inner. Wall,,and a spring'clip secured to said innerwall at the'inner side thereof, said spring clip having, apairof stopsfor defining V the operative andin'operative positions of said signalarm.
